Let's start with Sumana,fFrom the start she made sure that I had everything and she reponded very quickly for all my questions.
Away from the noisy crowded Bangkok, the unit itself is the right size for solo or for a couple. It has all the modern amenities for a comfortable stay. The nearest MRT is around 15 mins walk which I did once, the rest of the time I either took Grab or Uber which was quite cheap, it does take around 15 to 20 mins to get a car, so plan accordingly. 24 hours 7-eleven, several massages parlours (my favorite is Mai Tai Massage, about 7mins walk) and few cafes. One of my favorite art gallery - bangkok city city gallery is located on the way to Lumpini MRT.
Overall it was a good stay. Thanks Sumana!
